Let's divide 487493 by 81
We want to figure out the number of times 487493 can be divided by 81.

On to step 1:
81 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 81

Step 2:
81 goes into 48 0 times with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Grab the next digit (7) from the dividend, add it to 48, then carry on: 487 / 81

Advancing to step 3:
When dividing 487 by 81, we get 6 with a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 1 after subtracting 486 from 487.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 81

Advancing to step 4:
The number 81 fits into 14 0 times, leaving a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 60.0
Subtract 0 from 14 to get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 81

Let's proceed to step 5:
When dividing 149 by 81, we get 1 with a remainder of 68.
Write down 1 as next digit of the result. 
Result so far: 601.0
If we subtract 81 from 149, we get 68.
Append the next digit (3) from the dividend to 68 and continue with: 683 / 81

On to step 6:
81 can be fit into 683 8 times, resulting in a remainder of 35.
Write down 8 as next digit of the result. 
Result so far: 6018.0
Subtract 648 from 683 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 7:
The number 81 fits into 350 4 times, leaving a remainder of 26.
Write down 4 as next digit of the result. 
Result so far: 6018.4
Subtracting 324 from 350 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 8:
260 divided by 81 is 3 with a remainder of 17.
The next digit of our result is 3. 
Result so far: 6018.43
The remainder is 17 after subtracting 243 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 9:
When dividing 170 by 81, we get 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 6018.432
If we take 162 away from 170, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
When dividing 80 by 81, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 6018.432
Deduct 0 from 80 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 11:
When dividing 800 by 81, we get 9 with a remainder of 71.
Write down 9 as next digit of the result. 
Result so far: 6018.43209
Subtract 729 from 800 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 12:
The number 81 fits into 710 8 times, leaving a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 6018.432098
Deduct 648 from 710 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Step 13:
If we divide 620 by 81, we get 7 and a remainder of 53.
Write down 7 as next digit of the result. 
Result so far: 6018.4320987
If we take 567 away from 620, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Let's proceed to step 14:
81 goes into 530 6 times with a remainder of 44.
The next digit of our result is 6. 
Result so far: 6018.43209876
Deduct 486 from 530 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

After the division, we end up with 6018.43209876 and a remainder of 4.4e-08.
